Named native queries do not work with {{jakarta.persistence.Tuple}} return class. E.g. calling {{entityManager.createNamedQuery("Demo.findAllCustom", Tuple.class);}} in the test case, it causes following NullPointerException:
{noformat}Cannot invoke "String.toLowerCase()" because "aliases[i]" is null
java.lang.NullPointerException: Cannot invoke "String.toLowerCase()" because "aliases[i]" is null
